I'm resurrecting the creation I made quite some time ago for an answer to a PPCG post, as it seems quite a good fit to this celebration.
It is a digital clock design made on Conway's Game of Life (you know, with gliders and stuff).
Here is what otit looks like:
You can run the simulation and get the details of the design from here. Take the time to watch this, it's mesmerizing.
Now, I'll tell you the big secret about it: I actually built a time machine in 2017. I used it to jump one year and a half later, and saw this post. I thought: "Boy, do I want this watch.", so I went back in 2017 and made the post on PPCG so that I could refer to it when this celebration starts.
And the best part about it: The digital clock you're seeing is actually a part of the time machine. The whole machine is entirely built with Game of Life, and this is the time metering component. Unfortunately, I can't disclose the whole time machine design here, the world is not ready for that (besides, the license of the GoL-emulated flux capacitor is incompatible with the CC-BY-SA license).
